Vryburgia amaryllidis (Bouché) 

( Fig. 52View FIGURE 52)

Coccus amaryllidis Bouché, 1837: 99  . Coccus liliacearum Bouché, 1844: 300  . Pseudococcus lounsburyi Brain, 1912: 179  . Trionymus crini Hall, 1923: 11  . Pseudococcus (Trionymus) peregrinus Green, 1925: 40  . Chorizococcus microporus McKenzie, 1960: 699  .

DIAGNOSIS. Adult female elongate oval, more or less parallel-sided. Anal lobes well developed. Antennae 8 segmented. Legs comparatively large. Translucent pores numerous on hind femur and tibia. Cerarii present only on posterior 2 abdominal segments. Anal lobe cerarii each with 2 enlarged conical setae, plus 3–5 slender auxiliary setae and a small concentration of trilocular pores; penultimate cerarii with 2 slightly smaller conical setae, normally without slender auxiliary setae although rarely with 1 or 2 such setae. Circulus absent. Both pairs of ostioles well developed. Dorsal surface with slender setae; ventral setae also slender but a little longer than those on dorsum. Ventral multilocular disc pores present in midregion of abdomeninal segments IV –VII and posterior to vulva, occasionally also in lateral areas. Dorsal and ventral trilocular pores evenly dispersed. Dorsal and ventral discoidal pores minute, sparse. Dorsal oral rim ducts present in transverse rows across each abdominal segment and sparsely scattered over head and thorax. Ventral oral rim ducts present along lateral areas of most abdominal segments and in a cluster in lateral areas on meso- and metathorax. Dorsal oral collar ducts numerous across most abdominal segments; ventral dorsal oral collar ducts abundant in midregion of posterior abdominal segments forward to segment IV, and in lateral regions forward to head.

DISTRIBUTION: Afrotropical, Australasian, Nearctic, Palaearctic: Afghanistan, Bulgaria, Crete, Egypt, France, Germany, Iran, Israel, Italy, Netherlands, Portugal and United Kingdom. In Iran, V. amaryllidis  has only been recorded by Kozár et al. (1996). This mealybug is known from 6 host plant families worldwide (Ben-Dov et al., 2012).

COMMENTS. No material of V. amaryllidis  has been available for study in HMIM. Kozár et al. (1996) mentioned this mealybug without any date or locality. In the more temperate areas of the world, this species often causes concern in greenhouses on Liliaceae  , Iridaceae  and Agavaceae (Ben-Dov et al. 2012)  .
